I installed Garmin BlueChart Atlantic 2008.5 Unl0cked Mapsource Version on my PC.

under mapsource
utilities-
manage map products-

unlock regions-
add-
(I added the code from the .txt file)

The map now shows that it is "unlocked", but there are no details and no selectable sections.

I am new and trying to learn. Please be patient and try to help me.

Thanks!
